Lemierre's Syndrome: A Case Series

Abstract

Lemierre's syndrome (LS) is a potentially fatal complication of oropharyngeal infection, resulting in contiguous suppurative thrombosis of the internal jugular vein (IJV) and septic emboli. It is most commonly associated with Fusobacterium necrophorum (F. necrophorum), though other pathogens have also been implicated in its pathogenesis. The incidence of LS had so significantly decreased that it was referred to as "the forgotten disease." However, cases of LS have shown a resurgence, which may be partly attributed to an overreliance on a negative group A beta-hemolytic streptococcal rapid antigen detection test (RADT), commonly referred to as "rapid strep test." Clinicians must maintain a very high index of suspicion for LS in patients with persistent sequelae from tonsillopharyngitis who have a negative RADT.
